Author: Chad Versace <chad.vers...@linux.intel.com> Date: Thu Jan 19 13:08:48 2012 -0800 intel/gen6: Some framebuffers having separate depthstencil should be unsupported When the framebuffer has separate depth and stencil buffers, and HiZ is not enabled on the depth buffer, mark the framebuffer as unsupported. This happens when trying to create a framebuffer with Z16/S8 because we haven't enabled HiZ on Z16 yet. Fixes gles2conform test stencil8. Note: This is a candiate for the 8.0 branch.
